If there was one thing that you could change about your HP printer, chances would be that you would make the ink cartridges in it cost less. Luckily enough, for those who no longer want to keep spending enormous amounts of money on buying replacement ink cartridges, there are alternative, HP compatible ink cartridges available. Peachtree Ink for example sells re-filled generic cheap printer inks, both in black and tri-color ink. Re-filled ink cartridges are much less expensive than original HP ink cartridges, but there is nothing in terms of quality that separate the two.
